Introduction
The best time for women to take folic acid supplements is three months before pregnancy. Taking folic acid three months prior to conception allows folic acid levels to reach the standard concentration, ensuring that the egg is fertilized in an environment with adequate folic acid. When a woman's blood folic acid level reaches the normal range after supplementation, the resulting embryo has a reduced risk of fetal malformations.
There is no definitive best time for pregnant women to take folic acid, but it is generally recommended to start supplementation three months before conception. Women who are pregnant may experience folic acid deficiency or poor folic acid metabolism. Taking folic acid three months in advance can increase the level of folic acid in the mother's bloodstream, thereby reducing the risk of fetal malformations. Supplementing with an appropriate amount of folic acid at this stage helps raise maternal folic acid levels to the standard range, ensuring that the egg is fertilized in an environment with adequate folic acid concentration. Fertilized eggs formed after the mother’s blood folic acid levels have reached normal range due to folic acid intake are associated with a lower risk of fetal abnormalities. In addition to taking folic acid, women should also ensure sufficient sleep, moderate exercise, and a nutritious diet during preconception and pregnancy, while avoiding staying up late and excessive fatigue.
